Infrared Light for Memory Loss in Mild Cognitive Impairment (MCI)

Mild cognitive impairment (MCI) is a transitional risk state that occurs between the normal aging process and Alzheimer's dementia (AD). On average 32% of patients with MCI will progress to dementia, 62% will stay stable, and about 6% will return to normal cognition at subsequent visits. Current treatment for MCI includes cholinesterase inhibitors (donepezil, galantamine and rivastigmine), and NMDA receptor antagonists (memantine) which delay or slow the worsening of symptoms and treat cognitive symptoms (memory loss, confusion, and problems with thinking and reasoning). Despite currently ongoing drug studies and modest clinical benefits of currently approved drug treatments, there continues to remain a need for treatments for long term symptomatic improvement of MCI with fewer and less severe side effects. Photobiomodulation (PBM) therapy also called low-level laser (or light) therapy (LLLT) is a safe, non-invasive, non-thermal (no significant heat is generated) method of therapy which uses either visible red or near-infrared (NIR) light to stimulate, heal and repair damaged or dying tissue cells. This study proposes to use the Neuro RX Gamma device (version 2) to deliver NIR light energy to particular brain regions which are dysfunctional in MCI participants.
